Imagine that you are a doctor in a maternity ward. During your last shift, 20 babies were born. 10 had blue eyes, and 10 had brown eyes. Remember genotypes are the two alleles given for each trait, written with a letter. For this activity B =brown eyes b= blue eyes. Phenotypes are the physical appearance of the trait. Considering the possible genotypes you listed in question 3, what traits would the parents of brown-eyed and blue-eyed children have to have?
The allele for freckles (F) is dominant to the allele for no freckles (f). A freckled man and an unfreckled woman have two children, a boy with freckles and a girl without freckles. What are the genotypes for all four? Question 6 options: Mom: XfXf, Dad: XY, boy: ff, girl: ff Mom: ff, Dad: FF, boy: Ff, girl: ff Mom: ff, Dad: Ff, boy: Ff, girl: ff Mom: ff, Dad: FF, boy: Ff, girl: FF

A genetics researcher determines that the broad-sense heritability of height among Southwestern University undergraduate students is 0.90. Which of the following conclusions would be reasonable? Explain your answer. a. Sally is a Southwestern University undergraduate student, so 10% of her height is determined by nongenetic factors. b. Ninety percent of variation in height among all undergraduate students in the United States is due to genetic differences. c. Ninety percent of the height of Southwestern University undergraduate students is determined by genes. d. Ten percent of the variation in height among Southwestern University undergraduate students is determined by variation in nongenetic factors. e. Because the heritability of height among Southwestern University students is so high, any change in the students’ environment will have minimal effect on their height.
.A) To determine if a human trait is heritable, we would best study Group of answer choices. I think it's A. Please explain your answer I'm trying to understand the material a. monozygotic twins that were raised separately, in different environments. b. monozygotic twins that have been raised under similar conditions. c.only distantly related individuals. d. all males or all females. B). To say that a trait exhibits “high heritability” is to say that a. a given set of genes has no influence on a trait. b. there is no difference in genotype between members of the population at the loci in question. c. in a given environment and population, genetic differences have a high degree of influence on the trait compared to environmental influences. d. there is no difference in character between two individuals with the same genotype in question. C). If two populations with identical genetic makeup are raised in different environments, the narrow-sense heritability of a trait of…

Which of the following choices accurately describe what makes one person different from another with regard to traits (such as height) that have a very high heritability? Choose all that apply a) What makes us different is not that we have different genes, but that we have different alleles of many of those genes b) What makes us different from each other is that we have different genes from each other c) Random factors during development is the most significant causes of differences between people d) Most of us have exactly the same genes and alleles, and it’s the environment we were raised in that makes us different e) None of the other choices are accurate
